Raków Częstochowa has submitted an offer exceeding one million euros for 23-year-old Dutch-Brazilian defender Rio Hillen. NAC Breda has rejected the bid and is currently unwilling to cooperate with a transfer. NAC signed Hillen in July 2025 on a contract until mid-2029. The club has reportedly refused multiple approaches from the Polish club. Hillen, who has 5 caps for the Netherlands U19 team, is himself open to the move but is not permitted to speak with the media. It remains uncertain whether NAC will eventually cooperate on a transfer after turning down the initial offer. The player's current market value is estimated by Transfermarkt to be €600k.
